Description

"Equation" Equation PPT courseware 2

Fifty-five students from the fifth grade of Yunling Primary School performed the famous "Wood Drum Dance" of the Wa ethnic group in Yunnan, including 40 male actors and 15 female actors.

You can also use (55-15) people to express the number of male actors.

Number of male actors = total number of actors – number of female actors

40=55-15

Such a formula is called an equation in mathematics.

Can you find the equivalence relationship from the following information? Please express it as an equation.

1) The sum of the ages of the father and his son is x years. The father’s age is a years old, and the son’s age is b years. The father is 30 years older than his son.

2) The fruit store has 1,200 boxes of apples, 3,600 boxes of oranges, and 1,800 boxes of bananas. Oranges are three times as much as apples and twice as much as bananas.
